Should Your Family Eat This or That?

Pretzels or Cheerios?

The better choice: Cheerios.

When packing the ubiquitous snack bag to toss to a kid in a car seat (or to quiet a screamer in a stroller), choose the O's. Not only are they fortified with vitamins and minerals, but a one-cup serving also contains six milligrams of iron, which is just shy of a kid's daily allowance. Iron is crucial for development of the brain and the nervous system. In addition, Cheerios are made with whole grains and little sugar―a rarity in a cereal (or a snack, for that matter).
